I've got a 19" LCD - 'tis about 3-4 months old now... Not a problem at all!
One of the big things to look out for in an LCD is the dead-pixel return policy.
On an LCD, each 'pixel' is actually made up of 3 led's (Red, Green, Blue).
Now, if a company says that you must have at least 2 dead pixels before return, that means that you must have 2red, 2green, and 2blue all adjacent to eachother (usually).
Most companies have a policy where any 3 adjacent pixels (that is, a single red, green & blue, all adjacent) within the middle third of the monitor, and it's an instant return.
My monitor has a very nice return policy, sort of like that...
